Introduction to PTFE Lip Seal
PTFE (Polytetrafluoroethylene) lip seals are essential components in various industrial applications. PTFE is a high - performance polymer known for its excellent chemical resistance, low friction coefficient, high temperature resistance, and self - lubricating properties. A PTFE lip seal is designed to prevent the leakage of fluids, such as oil, water, or chemicals, while also keeping out contaminants like dust and dirt. These seals are commonly used in pumps, compressors, engines, and other machinery where reliable sealing is crucial for the proper functioning and longevity of the equipment.
